To my ear the best thing about the Peacock with Gg drones is the prominent clashing f#, which resolves to a d; it is a strongly emphasised note in the 'C major' strains. BP would have a high g nat here instead but Peacock was stuck with f# on NSP and seems to have gloried in it.
With Aa drones, f# dropping to d is just a d major chord - less exciting. John -- To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
